Benefits of technology

The present invention provides a tiled display device that creates a seamless visual experience by reducing the gap between multiple display devices. This prevents the user from recognizing boundaries or non-display areas between the devices and improves the sense of immersion in the image. The device achieves this by employing a reflective member to transmit light emitted from a light emitting element layer to the front of the display device through a substrate, while a pad portion is placed on the edge of the display device to minimize the non-display area.

Problems solved by technology

In case that the display device may be manufactured in a large size, a defect rate of the light emitting element may increase due to an increase in the number of pixels, thereby deteriorating productivity or reliability of the display device.

Abstract

A display device comprises a substrate including emission areas, and light blocking areas adjacent to the emission areas, a thin film transistor layer comprising a thin film transistor disposed on the substrate, and a connection line electrically connected to the thin film transistor, a light emitting element layer disposed on the thin film transistor layer and comprising light emitting elements corresponding to the emission areas, an encapsulation layer overlapping the light emitting element layer, and a pad portion disposed on the encapsulation layer and in electrical contact with the connection line through a contact hole in the encapsulation layer.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]This application claims priority to and benefits of Korean Patent Application No. 10-2020-0082331 under 35 U.S.C. § 119, filed on Jul. 3, 2020 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.BACKGROUND1. Technical Field[0002]The present disclosure relates to a display device and a tiled display device including the same.2. Description of the Related Art[0003]With the advance of information-oriented society, more and more demands are placed on display devices for displaying images in various ways. For example, display devices may be employed in various electronic devices such as smartphones, digital cameras, laptop computers, navigation devices, and smart televisions. A display device may be a flat panel display device such as a liquid crystal display device, a field emission display device and an organic light emitting display device. Among the flat panel display devices, in...
